nacl | Pure Go implementation of the NaCL set of API | Cryptography library

If I understand your question, you'll want something like:

Looking at the strace output for both root and greg, the problem seems clear.

For the root user, python 3.6 finds the libraries in /usr/lib64/python3.6.

However, for greg, it only looks under /usr/bin/python3 for subdirectories. That doesn't work because /usr/bin/python3 is a file.

I suspect that the user greg has PYTOHNHOME set erroneously to the location of the Python binary , and that is causing the issue.

Remove PYTOHNHOME from your environment, log out and log in again.

Note: the stuff below is probably barking up the wrong tree. I'll leave it for information.

The encodings module is an (undocumented) part of the python standard library. It is used by the locale module.

Based on the output I suspect that your Python installation has been damaged or corrupted. Try re-installing python.

EDIT:

If a forced re-install doesn't fix the problem, check that the directory encodings exist in your Python stdlib directory, and is accessible for all users.

To find out which directory that is:

The Python code uses sealed boxes, the Java/Groovy code does not, so the two are not compatible.

Since the generated ciphertexts are not deterministic, a direct comparison is not possible. A reasonable test is to decrypt the ciphertexts of both codes using the same code.
The following Python code uses the posted code for encryption and then performs decryption with the supplemented code. This code will be used to test the Java code later:

From aws_subnet_ids data source documentation, I see values within filter expects a set.

Looking code you are almost there, but you are passing a list of lists to values which is why you have this error.

element((var.nacl[*]["subnet_name"]), count.index) extracts list of subnets in the format of list.

All you need is to convert into set and pass without square braces like below..

This is mostly the same as the link you attached in your comment, but here is a more succinct example that may help

I finally find the solution. For people who facing the same trouble:

Here is the command I use for create the binary file:

There can be multiple Security Groups on a resource. When evaluating Security Groups, access is permitted if any security group rule permits access. If no Security Group rule permits access, then access is Denied.

There is only one Network Access Control List (NACL) on a subnet. When evaluating a NACL, the rules are evaluated in order. There is a default rule that is evaluated last, which determines whether the default is Allow or Deny.

I agree with you that the lecturer's statement appears inaccurate.

I suspect that by adding tuples, you meant to add the dictionary to the tuple of filters, which is not what you are doing in your current script. I suggest that you replace

Thanks for providing a concrete example on this, you're very close! The encoding is absolutely the issue here -- the pubkey is correctly encoded in Python as bytes. That first byte of \x90, encoded as two hex values, is 144 in JS, and you can check that in Python with: int('90', 16) = 144.

So to verify your key, you can instead use the base58 package https://github.com/keis/base58 and do:
